WHAT IS ROAD SAWING?

The most commonly used diamond cutting method – it has various applications ranging from cutting horizontal flat surfaces like floors, bridge decks and road pavements for drainage, laying out cables and electrical wires to removing damaged pavements sections and removing concrete sections for demolition purposes. The machines used for road sawing are called road saws and are of various types.

WHAT ARE THE TYPES OF ROAD SAWS THAT ARE USED?

Although, the choice of road saw depends on the job at hand, we’ll go through each instance and which of the variety to use:

Electric Road Saws: These road saws are ideal for places where ventilation is not adequate(confined spaces) and of course where there is a steady supply of electricity.

Diesel & Petrol Road Saws: This is used for situations where there is unsteady or no electric supply whatsoever, and should only be employed where ventilation is adequate.

Pneuamatic Pressure Road Saws: This works with pressurized gases. When pressure is exerted by a pressurized gas, the pneumatic system will draw what it need from the receiver to perform its function.

Hydraulic Road Saws: This runs by a controlled circulation of pressurized fluid, to an electric motor that converts it into mechanical output capable of doing work.

Road saws can also either be a hand-held tool or a big walk-behind saw.

SOME PRECAUTIONS ON USING THESE EQUIPMENTS

Road saws are very powerful tools and must be handled with care. Even a minor mistake can cause injury to you or people around you, so here are a couple precautions you can take note of to ensure you stay healthy and keep all your limbs.

Use Protective Equipments: This should not come as a shocker and is the most obvious precaution you can take to ensure your safety. A respirator is required when cutting dry concrete, safety glasses to avoid dust or stray material getting into your eyes, earplugs or earmuffs to protect your ears among other things.

Avoid Silica Dust:  When concrete is cut with an abrasive blade or a diamond blade, it generates a very fine dust. Some of these dusts contain silica dust which happens to be very dangerous when inhaled. Inhalation of large amounts of silica dust may lead to Silicosis.

Silicosis is a lung disease which could in turn cause lung fibrosis which has no known cure. A good number of construction worker die yearly from silicosis, so it’s probably a good idea to get a respirator when you want to use such equipment's. Wet saws or other types of vacuum systems can prevent silica dust from getting airborne.

Prevent Kickback or Lock in: Kickback refers to when the cutting saw jumps back at the operator. It usually happens when the operator tries to use the blade for a cut before the blade has started spinning at top speed. You can imagine the weight of the push if it’s a large saw and you’re not very heavy, so it’s a good idea to make sure the blade is at its top speed before using the blade for a cut.

Most concrete-cutting specialists consider core drilling in Sydney to be a standard service because it is a rapid, accurate, and clean method of drilling holes in concrete. What Concrete Core-Drilling Involves It is the technique of drilling perfectly circular holes in concrete walls, ceilings, floors, and other constructions that are known as concrete core drilling. This fine-tunes the concrete structure to accommodate modern conveniences such as phone lines, plumbing, HVAC ductwork, and sprinkler systems. Diamond core drills for concrete are the most frequently used tool for this process. On the drilling end, the core drill bit is typically made of a steel tube impregnated with diamond segments. The concrete coring drill is secured to the wall or floor in question using the rotating shaft of a concrete core drilling machine. Once the drilling is complete, a solid cylindrical concrete core, or "slug...

Technological Advancements in Concrete Cutting

Image
Do you know concrete cutting was necessary for backbreaking work in the early 1900s? Concrete saws were not available at that time. Cutters had to use basic tools like hammers and chisels to break concrete in those old days. Things were tough, tedious, and lengthy. Construction workers used to spend days and even weeks for Concrete Cutting in Campbelltown . However, the advanced concrete cutting technology has now changed completely. At present, you can cut concrete professionally and precisely within a few minutes with the help of power tools such as concrete saws. Advancements in Dry Cutting Wet cutting was the only used method to break concrete for the last many decades. It was preferred because it can keep the blades cool when they get hot during the process. Wet cutting also facilitated to control of the concrete dust to spread around. Initially, when dry cutting machines were evolved, the blades of the tool tore in about ten minutes because of intense temperatures produced during...
